1 Elaim.

The invention relates to a closure fastener, and more especially to adoor or window lock.

The primary object of the invention is the provision of a lock of thischaracter, wherein an eye hook is attached to a door or window frame, sothat when the hook is engaged with an eye it can be firmly and securelyheld in a fastening position making it impossible to unlatch the saiddoor or window from the outside.

Another object of the invention is the provision of a lock of thischaracter, wherein it is readily and easily applied in a usable positionfor the fastening of a door or window closed with security againstopening thereof, the lock being of novel construction and is unique inthe assembly of its parts, which are few in number.

A further object of the invention is the provision of a lock of thischaracter, which is simple in construction, thoroughly reliable andefficient in operation, readily and easily handled for locking andunlocking purposes, strong, durable, assuring safety in its use, andinexpensive to manufacture and install.

With these and other objects in view the invention consists in thefeatures of construction, combination and arrangement of parts as willbe hereinafter more fully described, illustrated in the accompanyingdrawing which discloses the preferred embodiment of the invention andpointed out in the claim hereunto appended.

In the accompanying drawing:

Figure 1 is a view showing a portion of a barrier and its frame, withthe lock constructed in acordance with the invention in lookingposition;

Figure 2 is a plan view of the lock;

Figure 3 is an edge elevation of the actuator for the lock.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, A designates generally a portion ofa horizontally swinging door, while B denotes generally a portion of adoor frame therefor, yet in lieu thereof may be a window assembly, asthe door and frame are merely shown for illustrative purposes in themounting of the lock constituting the present invention and hereinafterdescribed.

The lock constituting the present invention, comprises a hook member If]which has a bill I l for engaging in an eye 12, adapted to be properlysecured on the door A at the innermost side of the same, and this memberremote from the bill H is formed with an eye terminal [3, while next tothe latter is a substantially half-circular or arch bend i4.

Mounted on the frame B at the vertical side thereof is a rotor in theform of a Spool l5, which between the inner and outer spaced annularflanges l S and Il respectively, thereof is arranged an eccentric wristpin l8, it having axial mounting with the said flanges, and looselyengaged with this pin it is the eye terminal is of the member ill. Thespool i5 is hubbed on a screw l 9, which is fixed in the frame B for therotation of the rotor on a horizontal axis, as best seen in Figure 2 ofthe drawing.

The outer flange H is formed with finger engaging wings it so that therotor can be manually turned, and the bend l4 affords a clearance forthe hub of such spool 15 when the hook memher to has been engaged in theeye l2 and thereby holding the bill ll latched securely therein.

The latched position of the hook member In is clearly shown in Figure 1of the drawing and to release the bill from the eye l2 the spool i5 isturned clockwise eccentrically lowering the hook member l i] so that itcan be manually disengaged from the eye l2 by releasing the bill IItherefrom. When the spool i5 is turned counterclockwise the bill I l isurged into the eye I2, with the bend it underslung to the hub of thesaid spool, whereupon the said member in is firmly and securely latchedwith the said eye I2 so that the door cannot be opened or unlocked fromthe outside thereof.

What is claimed is:

A latch comprising a spool-like rotor, a screw adapted to pass throughthe core of the rotor to engage a closure member, a wrist pineccentrically and transversely mounted on said rotor, a hook member forengaging a keeper and pivotally mounted on said wrist pin, a bend in thehook member for the seating of the rotor therein when rotating in onedirection and underslung when the said member is engaged with thekeeper, and finger grips carried by the rotor for manual turningthereof.
